Linux founder Linus Torvalds may soon be using a proprietary, closed source code management tool for Linux kernel development, to the dismay of many in the open source community. Torvalds today diplomatically postponed his final decision, explaining that he's taking a week offline, and he says actively exploring alternatives to the Bitkeeper software that's served as his primary code management tool in recent years. Torvalds' announcement follows a decision by Bitkeeper's Larry McVoy yesterday that he would focus on the proprietary version of the software, orphaning the free client.
